Abstract
A switching physical layer (PHY) device comprises a first termination network, a switching transmitter, and a switching receiver. The first termination network communicates with a first network connector. The switching transmitter includes first and second outputs, which communicate with the first termination network and a second termination network, respectively. The switching transmitter selectively outputs a transmit signal to a selected one of the first and second termination networks based on a control signal. The switching receiver includes first and second inputs, which communicate with the first and second termination networks, respectively. The switching receiver receives a receive signal from the selected one of the first and second termination networks.
Claims28
A switching physical layer (PHY) device comprising:
- a first termination network that communicates with a first network connector;
- a switching transmitter that includes first and second outputs, which communicate with said first termination network and a second termination network, respectively, and that selectively outputs a transmit signal to a selected one of said first and second termination networks based on a control signal;
- and
- a switching receiver that includes first and second inputs, which communicate with said first and second termination networks, respectively, and that receives a receive signal from said selected one of said first and second termination networks,
- wherein said switching transmitter outputs a replica transmit signal based on said transmit signal to said switching receiver.
A switching physical layer (PHY) device comprising:
- a first termination network that communicates with a first network connector;
- a switching transmitter that includes first and second outputs, which communicate with said first termination network and a second termination network, respectively, and that selectively outputs a transmit signal to a selected one of said first and second termination networks based on a control signal;
- a switching receiver that includes first and second inputs, which communicate with said first and second termination networks, respectively, and that receives a receive signal from said selected one of said first and second termination networks;
